SPECIFICATION forming part of Letters Patent No. 641,938, dated January23, 1900.

Application iiled January 28. 1899. Serial No. 703,678. (No model.)

' vide the means for heating the raisins to b e seeded before they reachthe seeding` apparatus, the heating of the raisins softening them,rendering them more pliable, and also facilitating the extraction of theseeds. The heating device employed also avoids the necessity of steamingor wetting Ythe raisins before they are placed in the seeder, andconsequently, through the medium of the improved seeder, a higher gradeof product is obtained, and, furthermore, the product is not sticky orgummy.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth,

and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal vertical section through the hopper of themachine and the portion of the sieve connecting with the hopper. Y Fig.12t is a longitudinal vertical section through the body of the machine,being taken practically on the line 1a 1fL of Fig. 2. Fig. 2 is avertical transverse section through the body of the machine, takensubstantially on the line 2 2 of Fig. 1a. Fig. 3 is a detaillongitudinal section-through a portion of the carrying-roll and aportion of the brushes used in connection with said carrying-roll. Fig.4 is a transverse section through the body portion of the carrying-roll,illustrating a segment of asaw or seed carrier attached thereto; andFig. 5 is a vertical section through one of the shafts, illustrating oneof the brushes for the carrying-roll in position thereon.

A represents the frame of the body of the machine, which consists of twovertical side pieces that are connected or braced in any 'suitable orapproved manner.

B represents a hopper that is removed some distance from the frame A andis at a greater elevation than the upper portion of the said frame. Thehopper B is connected with the frame by side pieces 10. (Shown in dottedlines in Figs. 1 and 1ZL and in transverse section in Fig. 2.) Thehopper is preferably supported by means of suitable legs 11, and Withinthe hopper a drum 12 is mounted to revolve, adapted to receive theraisins to be seeded and conduct them to a reciprocating screen B'. Theupper portion of the hopper is inclined in direction of the drum 12,such yinclination being produced by employing a fixed back board 13,inclined from the topV downwardly and inwardly, and an opposite frontboard 14, that is'given a like inclination, but is adjustable inslideways 15. These front and back boards direct the raisins to the drum12, the inner or lower ends of the boards4 being adjacent to the upperportion of the said drum, and the amount of raisins fed to said screenB' of the drum is regulated by the manipulation of the adjustable frontboard 14. The shaft 16 of the drum 12 is provided at each of its outerends with a crank 17, and uprights 18 are secured to the side boards 10,connecting the hopper with the body of the machine, the said uprightsbeing in pairs, and preferably one pair of uprights is located near thehopper and the other pair near the body of the machine, as shown inFigs. 1 and 1a. Each upright is pivotally connected at its upper end toa link 19, and the pairs of links are connected at their lower ends by across-bar 20. The screen B' rests upon or is attached to the cross-bars20, connecting the links, and said screen is further connected with orrests upon a third crossbar 21, intermediate of the cross-bars 20, thecross-bar 21 being attached at its ends to pitmen 22, said pitmen beinglikewise mounted upon Ithe cranks 17 of the drum-shaftl, as

IOO

A, as is illustrated in Fig. 2. The screen B' consists of side pieces 23and a bottom that is constructed of a series of longitudinal bars 24,A-shaped in cross-section, the bars being attached to or made to restupon the crossbars 2O and 21. A space intervenes the 'varions bottombars 24 of the sieve, said spaces being of sufficient width to permit ofnails or other' foreign matter being discharged from the screen whilethe raisins are passing down the screen, the screen being reciprocatedby the rotation of the shaft 16, which maybe accomplished in any desiredway.

In the construction of the body portion of the machine a hollow heatingdrum or roll C is employed, located immediately beneath the deliveryendof the screen B'. The trnnnions of the heating-roll are journaled inboxes 25, mounted in the frame A, as shown in Fig. 2, one trunnion,2G,being usually solid and the other trunnion, 27, tubular, in orderthat a pipe 28, connected with a source of steam-supply, may beintroduced through the hollow trunnion into the interior of the Saidheatingroll, the pipe 28 being provided with a suitable valve 29.Set-screws 30 are attached to the boxes 25, provided for theheating-roll, as shown in Fig. 1a, in order that the said boxes may belaterally adjusted.

Immediately below the heatingroll C a shaft 31 is journaled in suitableboxes 32, re-

` movably located in the frame A. The shaft 31 is provided with alongitudinal keyway 31, as shown in Figs. l and 3. A vseries of disks ismounted upon the shaft 31, eachdisk being provided with a featheradapted to enter the keyway 31, and the boxes 32 are' held in positionon the shaft 3l by plates 34, slid through the members of the frame A toan engagement with the rear portions of the boxes, and when the saidplates are removed the boxes and shaft and the disks carried thereby maybe removed from the frame A. The disks 33, when mounted on the shaft 3l,constitute what may be termed a releasing device, since the said disks33 are adapted to enter the seed-retaining sections of a carrying-rollto be hereinafter described, which latter roll is adapted to receive theraisins and extract the seeds therefrom, the releasing device serving todisengage the seeded raisins from the carrying-roll. This releasingdevice, however, does not constitute a feature of my invention, as anyadaptable device may be substituted therefor; but when the disks 33 areemployed their edges are serrated or otherwise roughencd, although shownplain in the drawings.

The carrying-roll D occupies a central position in the frame A, beingalso below the heating-roll C and in front of the releasingroll. Thecarrying-roll D consists of a tubular body 35, secured at each end to ahead 36, as shown in Fig. 3. A shaft 37 is passed through the heads 36,the outer ends 38 of the shaft 37 being preferably of less diameter thanthe diameter of the body portion of the shaft. The body portion of thecarrying-roll D is arrangedto receive at each of its ends a cap 39, thecaps being held in position by nuts 40, screwed upon the outer ends ofthe body portion of the shaft 37, as is also shown in Fig. 3.

The ends 38 of the shaft 37 are journaled in bearing 41, located in theframe, the bearings being removable at the rear portion of the frame,and the bearings4l are held in place by plates 42, slid in suitablerecesses in the frame, and by set-screws 43, passed through said platesto an engagement with said bearings, as shown in dotted lines in Figs. land 2.

Dovetail grooves 44 are longitudinally made in the outer surface of thebody of the carrying-roll D, as shown in Figs. la and 4. The body of thecarrying-roll is adapted to receive a series of saws 45 or serratedrings adapted to remove the seeds from the raisins. These saws orserrated rings are preferably made in segments, as shown in Figs. l and4, and each segment is provided with a dovetail lug 47, adapted to enterone of the dovetailed grooves 44 in the body of the carryingroll, andeach segment is also preferably provided with a dovetail groove 46 atone end and a dovetail projection 4Gn at the opposite end, as also shownin Fig. 4, so that the various segments of a saw or serrated ring may befirmly, conveniently, and Aexpeditiously connected to form a circle. Theobject of constructing the saws in segments is to save expense inreplacing damaged sections of the saws, since should abreak occur in anysegment of any sawsuch segment may be removed and replaced by a perfectsection, thus obviating the necessity of substituting a complete perfectsaw.

The disks 33 of the releasing-roll enter between the saws or serratedrings 45 of the carrying-roll, and the said saws or rings are suitablyspaced by washers 48, as shown' in Fig. 3, and the saws and washers arefirmly held upon the body of the carrying-roll by the caps 39, whichcaps engage with the outermost saws on the roll. Immediately below thecarrying-roll D a shaft 49 is journaled in the frame A, the longitudinalaxis of the shaft 49 being in vertical alinement with the ilongitudinalaxis of the shaft 37 of said carryingroll. The shaft 49 is provided witha longitudinal keyway 50, as shown in Figs. la and 5, and the said shaft49 carries a series of brushes. The brushes 'consist of metal disks 51,arranged to slide upon the shaft 49, each disk being provided withperipheral teeth and with a suitable projection arranged to enter thekeyway of the shaft 49. The serrated disk brushes 51 are separated bywashers 52, the separation of the serrated disk brushes being such thatthe said brushes will be beneath the toothed portion of saws on thecarrying-roll D. The hub portion 53 of a stripper 54 is loosely mountedupon each of the washers 52, the hubs of the strippers being of lesstransverse thickness than the trans- IOO IIO

verse thickness of the washers, and the strippers 54, projected from thehubs 53, consist of downwardly-curved arms, as shown in Fig. la, whicharms bear against a rod 55, extending from side to side of the frame 'atthe rear of the strippers. Thus it will be observed that the shaft 49will revolve while the strippers 54 remain stationary.

The disk brushes and washers are held on the shaft 49 by means oflock-nu ts 56, screwed upon said shaft, and the ends of the shaft arejournaled in boxes 57, located in the frame A, which boxes arevertically adjustable, so that the disk brushes may be carried toward orfrom the saws of the carrying-roll. The shaft 49, provided with the diskbrushes, revolves in the same direction as the shaft 37 of thecarrying-roll, as indicated by the arrows in Fig. la; but at the pointwhere the peripheries of the disks 5l and saws 45 oppose each other saiddisks and saws move in opposite directions. The shaft 3l of thereleasing-roll and the shafts 37 and 49, provided for the carrying-rolland disk brushes, may be driven in any desired manner.

A series of shafts 59 is grouped around the carrying-roll, the uppermostshaft being adjacent to the heating-roll C and the lower shaft 59 beingopposite to the front central portion of the carrying-roll. A roller 58is mounted to revolve with each shaft 59, and each shaft 59 is receivedby boxes 60, adjustably mounted in the frame A, the adjustment of saidboxes 60 being accomplished through the medium of set-screws 6l or theirequivalents. The rollers 58 may be provided with resilient surfaces.

The compressing-roller 58, adjacent to the roll or drum C, is so placedthat the raisins delivered to said roll or drum C from the screen B orother source of supply will pass between the upper compressing-roller 58and said roll or drum C. This roll or drum C, which constitutes,primarily, a press-roll and which I prefer to heat, as stated, acts inconjunction with the upper compressing-roller 58 or any equivalent ofsuch roller and subjects the raisins to heat, flattens the same withoutthe aid of adventitious moisture, pushes the pulp away from the seeds,and so prepares the raisins thatone impression of the im paling orcarrying roll D will break the skins and leave the seeds exposed, sothat the brushes 5l can readily strip the seeds from the impaling-roll,while the seeded raisins may be removed from the impaling-roll by anydesired form of releasing device. IThe addition of heat to thepress-roll C contributes to the end desired, and for this reason theheat is preferable.

In the operation of the machine the raisins to be seeded are placed inthe hopper without being steamed, or, if desired, without having beensubjected to the action of water and are fed by the drum l2 to thescreen B, the said screen serving to separate the extraneous matter fromthe fruit, as stated.

The raisins are delivered by the screen to the heating-roll C, wherethey are softened by contact with said roll, and the raisins then passbetween the heating-roll C and adjacent pressure-roll 58 and fall. uponthe carryingroll D. The raisins are forced by the pressure-rolls intothe spaces between the sawsections of the carrying-roll and the seeds ofthe raisins will be received by the teeth of said saw-sections. As thecarrying-roll continues to revolve the raisin-seeds are removed from theteeth of the saw-sections of the carrying-roll by the serrated diskbrushes 51 and the seeds are removed from these disk brushes by thestrippers 54, the seeds fallingl to the floor or support upon which themachine is placed or into a receptacle provided to receive them. Theraisins continue on the carryingroll until they are met by the disks 33of the releasing-roll, which disks act to remove the seeded raisins fromthe carrying-roll, the seeded raisins dropping downward at the rear ofthe machine.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- I. In a raisin-seeder, a heating-roll adapted toreceive the raisins to be seeded, a carrying-roll arranged to receivethe raisins from the heating-roll, the carrying-roll being provided withperipherally-toothed rings held separated,brushes located adjacent tothe carrying-roll, and adapted to take the seeds from said roll, and adevice for removing the raisins from the carrying-roll, as described.
